Secrets for Chandrila
Maybe I got the name of the planet wrong, but it's the first mission on the third tier, where you're in the tomb of the jedi. I didn't see the answer to this one anywhere, but at the very beginning (before you use Force Push to move the boulder), you can use Force Sense to see a strange symbol on the right wall by the boulder. I've tried push, pull, lightning, and every other force power at my disposal to try to activate that thing. I've attacked it, wall-flipped off of it, and generally tried to kick its ass. Nothing seems to affect that symbol. Is it even there for a reason?
